Problems solved by technology

[0053] However, in a wireless communication system in which a base station apparatus and a mobile station apparatus communicate using subbands for uplink and downlink, in the conventional HARQ indicator channel arrangement, the mobile station apparatus that limits the subband sometimes cannot Problems receiving HARQ indicator channel
That is, a mobile station device with a limited subband can receive a HARQ indicator channel when a HARQ indicator channel is configured in a subband in which the mobile station device can be used, but a HARQ indicator channel is configured in a subband in which the mobile station device cannot be used. channel, there is a problem that the HARQ indicator channel cannot be received
[0054] Furthermore, in conventional HARQ indicator channel group configuration, a mobile station device that can use a plurality of downlink subbands cannot know in which of a plurality of subbands that can use the downlink of the mobile station device, HARQ is configured. Indicator channel, and there is a problem that the HARQ indicator channel cannot be received

Embodiment Construction

[0115] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The wireless communication system of this embodiment includes a plurality of mobile station devices 2 and a base station device 1 . A plurality of mobile station devices 2 and base station devices 1 transmit and receive signals (information) to each other through wireless communication. The downlink of wireless communication from the base station apparatus 1 to the mobile station apparatus 2 includes a downlink shared data channel, a control format indicator channel, a HARQ indicator channel, a broadcast channel, a downlink control channel, and a downlink pilot channel. Furthermore, the uplink of wireless communication from the mobile station apparatus 2 to the base station apparatus 1 includes an uplink control channel, an uplink shared data channel, and an uplink pilot channel.

Abstract

A base station device, which allocates one or more subbands of each of an uplink and a downlink to a mobile station device and transmits response information, which indicates whether or not uplink data from the mobile station device has been properly received, to the mobile station device, the base station device includes: a control unit (11) which controls an arrangement of a response information group including multiple pieces of response information directed to a downlink subband allocated to the mobile station device; and a multiplexing unit (160) which collects the same type of multiple pieces of response information to configure the response information group, and arranges the configured response information group in the downlink subband based on the control of the control unit.
